17、acteristics of the product and the proper methods of safely handling full, partially full, and empty cylinders.5.2.2 Facility personnel must be trained in applicable standards CFR Title 49, Part 173 and CFR Title 49, Part 178, and CGAStandards C-1, C-4, C-6, C-7, and P-1.5.2.2 IG-100 handling shall

18、be in nonsmoking, heater-free, ventilated areas to preclude product accumulation. Provisions shallbe made to ensure that service areas limit IG-100 concentrations to not exceed 52 % (10 % Sea Level Oxygen equivalency) for30 s and 7 % (19.5 % Sea Level Oxygen equivalency) for 8 h.5.2.3 Cylinders shal

19、l not be overfilled. Filling density requirements are specified in CFR Title 49, Part 173 (173.302).5.2.4 Cylinders shall be free of dirt and contamination that would contribute to or would cause deterioration of product duringshipment or storage. Precautions should be taken to prevent the entry of

21、minimum design pressure requirements shall be as indicated in CFR Title 49, Part 173.301. The pressure inside thecontainer at 70F (21C) shall not exceed the service pressure for which the container is marked. The pressure inside the containerat 130F (54C) shall not exceed 5/4 times the service press

22、ure for which the container is marked. Fig. 1 and Fig. 2 illustrate theeffect of temperature on cylinders filled with IG-100.5.3.2 Transportation shall be by suitable vehicles to preclude cylinder damage by excessive mechanical vibration, shock,freezing, or deleterious high temperatures throughout t
